Very simple particle effect

[Petr Schreiber]

Hi,

I just realized I haven't released any example of
particle effect .

So here is little one, more complex will follow.
Have fun!

Hi,

this is another particle effect. The first was similar to fire or explosion,
this is similar to ... well don't know, maybe some scary dream

Let this demo run for a while, the animation is quite dynamic; it could be used as not-dependent visualisation when listening music

Please keep in mind, that this demo is more complex, so faster computer
is fine. But when in serious troubles just decrease the number of particles in the source. Runs OK on 850 MHz processor and Radeon 9600 with default settings.

To achieve maximum visual quality, set your desktop bit depth to 32.


Have fun

Didnt see the point of starting a new topic but I wanted to post.

I feel a bit cheated, particle effects always impressed me until I see how you can do them.

I thought that every pixel in the effect was tracked and drawn but I see you can use a texture map quad and apply some simple effects.

still looks good though.

I've seen many different types... mostly this is the common way I see. But I have seen where the particles can be poly drawn shapes only or even points. And of course you can mix and match all of the above to make or get the look you want. In most of the really cool looking effects you usually see a few effects combined to make one great overall effect.

Hi Abraxas,

so you thought particle is 3D volume?

This is also the way - I suspect that in "Fable" game, in some scenes they used 3D texture filled with some grayscale noise and then as you pass through it interpolates across the "slices".

In othe cases it is quite common to use set of billboards( polygons always facing camera) to fake clouds for example.

I like particle effects a lot, but be warned they easily differentiate low and high end graphic cards Blending operations are usually a lot slower on low end cards. I remember my brother cursing ... simply all when in game he played started to snow. Lot of particles, and performance got down. Of course, that was in times of GeForce2 ...

I can prepare article on this topic if you are interested.


Bye,

Would be interesting but Only if you have time.
